Abstract (en)

1. Device for precise adjustment of the relative angular positioning of the shafts driving the shaping wheels of a rotary forging machine, said shafts (2, 3) rotating in the same direction and synchronously, being integral with helical teethed gears (10, 11) in constant engagement with conjugate helical teeth (8, 9) one gear being coupled to a driving device (1), one other gear being also movable in coaxial translation and connected to a micrometric device (12 to 24) for adjusting its axial position, which device enables to determine the relative angular positioning of said two gears, characterized in that said two gears are driven separately and respectively engaged with two driving gears (8, 9) with paired helical teeth of symetrical inclination and coaxially integral one with the other, the two driven gears (10, 11) being immobilized in axial translation, whereas the assembly of the two driving gears is movable in coaxial translation and cooperates with the micrometric adjusting device.

Abstract (fr)

Le dispositif comporte, accouplés à au moins deux arbres (2, 3) porte-molettes devant tourner dans le même sens et en synchronisme, des engrenages menés à denture hélicoïdale (25, 26) en prise constante avec au moins un engrenage menant à denture hélicoïdale, conjuguée (27) qui est accouplé à un dispositif moteur (1), l'un au moins de ces engrenages étant mobile en translation coaxiale et relié à un dispositif de réglage micrométrique (28 à 35) de sa position axiale qui permet en fonction de la pente d'inclinaison des dentures, de déterminer le calage angulaire relatif des deux engrenages menés.
